1995 GMC Jimmy - Page 2 - Answered Questions & Fixed issues

Harold, one of the vent door actuators is probably stuck holding heater doors open, or the duct work may have come apart under dash. "I hope this helped you out, if so let me know by pressing the helpful button. Check out some of my other posts if you need more tips and info."

I had a 1999 gmc jimmy and mine was on the top of the fuel pump which is on top of gas tank

Check all shift linkage under truck for loose bushings. Check also for bad transmission mount, engine mounts, bent linkage, etc. Also can be a problem inside transmission, often able to be fixed in the car by removing the trans lower pan to make repairs.

try to spray fuel in the tbi if it has one and see if it starts if it does you either have a plugged fuel filter or a bad fuel pump.

there is no vacuum lines to transmission the problem with the first gear only you have to retrieve the code of transmission problem first and take trans. o?l level

Have someone crank it for you while you bang on the bottom of fuel tank. If it starts, replace pump.

Are you sure you are listening to a stereo program (e.g. FM radio or CD/Tape)? Have you tried adjusting the fade and balance controls? If sound is not coming out of all speakers, you will probably have to replace the radio.

All of the transmission fluid can leak out. The cooling lines are there to cool the tranny fluid, and it is circulated through the radiator by means of a pump. If a line is leaking, the pump will just empty the fluid out through the leak. The lines are usually just held in place by clamps to keep them from chafing through against the body or chassis, so replacing them should be quite an easy job. Just undo the bolts that hold them to the box and the radiator, undo however many clamps hold them in place, and reverse the procedure with new pipes.

The lines are different sizes and if you did... it would dead-head the pump and not start! If you need further help, I’m available over the phone at https://www.6ya.com/expert/eric_5179db65226039e7

Could be bad 3-4 shift solenoid. Drop trans pan to inspect. These solenoids often come apart and are easily seen to be bad.

There ar various sizes , measure the existing ,

Very bad issue, and could be dangerous. Most likely cause bad fuel injector stuck open. This can ruin engine bearing so drain oil and replace while also fixing leaking injector.

Tighten the bands.

It sounds like a faulty fuel pressure regulator. When you turn the key to the on position the fuel pump starts for an instant to build pressure in the fuel line. If the pressure regulator has allowed too much leakage since the last start then the fuel pump does not have enough time to prime the line. The fuel pressure will still measure ok when the car is running because the leakage is very low. Try turning the key off and on a few times prior to starting and see if the extra pump priming steps help. Also check the vacuum line to the regulator because it needs vacuum to work correctly.

why did you replace dist? What was the original concern?

if stuck open, vehicle will have very rough idle

check operation of vacuum diaphragm under battery that actuates 4WD cable

rotors?

If it came of the same size engine and is also a 4X4 it should work if not the same size engine the computers are different and will not work

Still sounds like a vacuum problem - not enough vacuum to hold the solenoid in. You could try directly applying a good vacuum source (either connecting to a good line on the truck or using a vacuum pump) to see if the solenoid is working properly. If that works, you will need to recheck ALL vacuum lines. You could also check for DTCs to see if it might be a computer problem.
